Metadata-Version: 1.1 Name: peewee Version: 2.8.4 Summary: a little orm Home-page: http://github.com/coleifer/peewee/ Author: Charles Leifer Author-email: coleifer@gmail.com License: UNKNOWN Description: .. image:: http://media.charlesleifer.com/blog/photos/p1423749536.32.png peewee ====== Peewee is a simple and small ORM. It has few (but expressive) concepts, making it easy to learn and intuitive to use. * A small, expressive ORM * Written in python with support for versions 2.6+ and 3.2+. * built-in support for sqlite, mysql and postgresql * tons of extensions available in the `playhouse <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html>`_ * `Postgresql HStore, JSON, arrays and more <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#postgres-ext>`_ * `SQLite full-text search, user-defined functions, virtual tables and more <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#sqlite-ext>`_ * `Schema migrations <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#migrate>`_ and `model code generator <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#pwiz>`_ * `Connection pool <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#pool>`_ * `Encryption <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#sqlcipher-ext>`_ * `and much, much more... <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html>`_ .. image:: https://api.travis-ci.org/coleifer/peewee.png?branch=master :target: https://travis-ci.org/coleifer/peewee New to peewee? Here is a list of documents you might find most helpful when getting started: * `Quickstart guide <http://docs.peewee-orm.com/en/latest/peewee/quickstart.html#quickstart>`_ -- this guide covers all the essentials. It will take you between 5 and 10 minutes to go through it. * `Guide to the various query operators <http://docs.peewee-orm.com/en/latest/peewee/querying.html#query-operators>`_ describes how to construct queries and combine expressions. * `Field types table <http://docs.peewee-orm.com/en/latest/peewee/models.html#field-types-table>`_ lists the various field types peewee supports and the parameters they accept. For flask helpers, check out the `flask_utils extension module <http://docs.peewee-orm.com/en/latest/peewee/playhouse.html#flask-utils>`_. You can also use peewee with the popular extension `flask-admin <https://flask-admin.readthedocs.io/en/latest/>`_ to provide a Django-like admin interface for managing peewee models. Examples -------- Defining models is similar to Django or SQLAlchemy: .. code-block:: python from peewee import * from playhouse.sqlite_ext import SqliteExtDatabase import datetime db = SqliteExtDatabase('my_database.db') class BaseModel(Model): class Meta: database = db class User(BaseModel): username = CharField(unique=True) class Tweet(BaseModel): user = ForeignKeyField(User, related_name='tweets') message = TextField() created_date = DateTimeField(default=datetime.datetime.now) is_published = BooleanField(default=True) Connect to the database and create tables: .. code-block:: python db.connect() db.create_tables([User, Tweet]) Create a few rows: .. code-block:: python charlie = User.create(username='charlie') huey = User(username='huey') huey.save() # No need to set `is_published` or `created_date` since they # will just use the default values we specified. Tweet.create(user=charlie, message='My first tweet') Queries are expressive and composable: .. code-block:: python # A simple query selecting a user. User.get(User.username == 'charles') # Get tweets created by one of several users. The "<<" operator # corresponds to the SQL "IN" operator. usernames = ['charlie', 'huey', 'mickey'] users = User.select().where(User.username << usernames) tweets = Tweet.select().where(Tweet.user << users) # We could accomplish the same using a JOIN: tweets = (Tweet .select() .join(User) .where(User.username << usernames)) # How many tweets were published today? tweets_today = (Tweet .select() .where( (Tweet.created_date >= datetime.date.today()) & (Tweet.is_published == True)) .count()) # Paginate the user table and show me page 3 (users 41-60). User.select().order_by(User.username).paginate(3, 20) # Order users by the number of tweets they've created: tweet_ct = fn.Count(Tweet.id) users = (User .select(User, tweet_ct.alias('ct')) .join(Tweet, JOIN.LEFT_OUTER) .group_by(User) .order_by(tweet_ct.desc())) # Do an atomic update Counter.update(count=Counter.count + 1).where( Counter.url == request.url) Check out the `example app <http://docs.peewee-orm.com/en/latest/peewee/example.html>`_ for a working Twitter-clone website written with Flask.

Still want more info? --------------------- .. image:: http://media.charlesleifer.com/blog/photos/wat.jpg I've written a number of blog posts about building applications and web-services with peewee (and usually Flask).
